Left Ventricular Volumes with Ventricular Inhibited and Atrial Triggered Ventricular Pacing
Acta Medica Scandinavica, 1983ABSTRACT Left ventricular (LV) volumes were assessed with equilibrium radionuclide angiocardiography at rest and during exercise in nine patients with high‐degree AV block treated with ventricular inhibited pacing (VVI), which was subsequently changed to atrial triggered ventricular pacing (VAT). The ventricular rates were similar at rest but higher on

Circulation, 1971 Ventricular fibrillation is the most common mechanism of sudden unexpected cardiac death in persons with asymptomatic or symptomatic coronary artery disease. The electrophysiologic mechanisms reviewed in this article include: automaticity of pacemaker fibers, transformation of nonpacemaker into pacemaker fibers, "injury" currents and reentry.

Ventricular Strain and Ventricular Hypertrophy
New England Journal of Medicine, 1949WHEN medical terminology was less precise the expression "strained heart" was employed at times to describe obscurely but ominously diseased hearts.

Left ventricular involvement in right ventricular dysplasia
American Heart Journal, 1992Right ventricular dysplasia, a heart muscle disease of unknown cause, anatomically characterized by variable replacement of myocardial muscle with adipose or fibroadipose tissue, is usually considered a selective disorder of the right ventricle. However, concomitant left ventricular involvement has been noted in a few cases.

Ventricular safety pacing, ventricular sense response, and ventricular tachycardia
Heart Rhythm, 2010The ventricular sense response (VSR) algorithm enforces biventricular pacing on ventricular sensing to maximize biventricular pacing in patients with atrial fibrillation. This report describes a case of recurrent ventricular tachycardia that may be facilitated by this enforced pacing algorithm.

Early premature ventricular beats, repetitive ventricular response, and ventricular fibrillation
American Heart Journal, 1967Abstract Three cases are reported in which early premature ventricular beats were followed by ventricular fibrillation (2 cases) and repetitive ventricular responses (1 case). The relationship of these findings to the vulnerable phase is discussed.

Child's Nervous System, 2003
Ventricular dilatation is generally defined on ultrasounds (US) or MRI as an atrium larger than 10 to 12 mm on axial or coronal planes. After 22 weeks, this measure is independent of the term.In the view of the prognostication, it is of utmost importance to not only calculate the width of the ventricles but also to estimate the progression of the ...

Progress in Cardiovascular Diseases, 1980
T HIS STATEMENT by John Mackenzie is still, in its widest sense, applicable today. Yet scientific knowledge has progressed to such a degree, and electrocardiographic diagnosis has become so much more refined, that there are now many new criteria by which premature ectopic impulse formation may be analyzed and evaluated.

Medical Clinics of North America, 2019
Ventricular tachycardia is commonly seen in medical practice. It may be completely benign or portend high risk for sudden cardiac death. Therefore, it is important that clinicians be familiar with and able to promptly recognize and manage ventricular tachycardia when confronted with it clinically. In many cases, curative therapy for a given ventricular

Radiologic Clinics of North America, 1999
Multiple modalities contribute to the evaluation of ventricular function. The role of cineangiography, echocardiography, MR imaging, ultrafast CT, and nuclear medicine continue to evolve and improve our understanding of the physiology and pathophysiology of ventricular function. This article discusses the use and limitation of each modality.
